I've sent airsoft guns Regular Parcel as well as XpressPost, and haven't had a problem. (I've sent about 6 guns).

All four of my airsoft guns and one of my old pellet guns came xpresspost. Not to mention every add I've seen on here says "Blah blah price shipped xpresspost" So it seems EVERYONE is doing it? My question is do I just package it up, walk into to the post office and say, "need to ship this xpress post" they weigh it, I pay and walk out? Is it that simple?
